Internal stress is a duck on water – from the top, he’s smooth sailing, but underneath the water, they are treading water fast.

External stress is just that – they’re verbalizing stress to everyone; they’re publicly anxious; they might cry or leave work early – something big, noticeable, external.

How do they learn? You can’t just assume that everyone hates learning; a lot of people love and thrive on the opportunity to learn, especially as they get older and they want to stay valuable and competitive in the workforce.
